How can you tell SMART is enabled on a drive from the command output?

• A. Output shows: 'SMART support is: Enabled'
• B. Output shows: 'SMART is active'
• C. Output shows: 'SMART ready'
• D. Output shows: 'Disk health: Good'

Answer: (A)

SMART status is shown by a line that directly states whether SMART is enabled on the device. When the command output includes “SMART support is: Enabled,” that confirms SMART reporting is active for that drive. This is the clearest indicator because it tells you the feature is turned on and ready to provide attributes and health data.

Other phrases like “SMART is active,” “SMART ready,” or “Disk health: Good” don’t definitively indicate that SMART is enabled. The health line reflects the current health assessment, not whether SMART is enabled, and the other phrases aren’t standard indicators of the enablement state. To verify, run a command such as smartctl -a /dev/sdX and check for the line showing SMART support is: Enabled. Once enabled, you can review the SMART attributes and overall health status.
